    This paper presents the results of a Pt/n-GaN Schottky contact technology development based on electrochemical metal deposition. Three different technological approaches are used to fabricate GaN varactor diodes. The effects ...
  • TIGINYANU, Ion (Academica Greifswald, 2017)
    GaN and ZnO are wide band gap semiconductor compounds with unique properties favourable for the development of short-wavelength light emitting devices and high-power electronics. From the point of view of applications, ...
  • POPA, V.; TIGINYANU, I. M.; URSAKI, V. V.; VOLCIUS, O.; MORKOÇ, H. (IOP Publishing, 2006)
    We demonstrate that photoelectrochemical (PEC) etching of GaN layers in KOH or H3PO4 solutions leads to the formation of specific surface morphologies which cause the material to exhibit different sensitivities to certain ...
  • ALBU, Sergiu; MONAICO, Eduard; TIGINYANU, I. M.; URSAKI, V. V. (Institutul de Fizică Aplicată, AŞM, 2006)
    The interest in nanometer-scale materials and devices stimulated the development of alternative technologies in recent years. Metal nanowires are one of the most attractive materials because of their unique properties ...
  • TSIULYANU, D.; MARIAN, S.; MOCREAC, O. (Institutul de Fizică Aplicată al AŞM, 2012)
    In this paper, the change of work function ( Δφ ) of the tellurium thin films was studied in response to different concentrations of nitrogen dioxide, carbon oxide, ozone and water vapor using a KP with a gold grid reference ...
  • TSIULYANU, D.; MARIAN, S.; MOCREAC, O. (Academy of Sciences of Moldova, 2012)
    The sensing behavior of tellurium films at room temperature was tested with environmental pollutant gases, such as NO2, CO, O3, and water vapor, using the Kelvin probe technique. A significant sensitivity was observed for ...
  • TSIULYANU, Dumitru (Beilstein Institute for the Advancement of Chemical Sciences (Germany), 2020)
    Nanocrystalline and amorphous nanostructured tellurium (Te) thin films were grown and their gas-sensing properties were investigated at different operating temperatures with respect to scanning electron microscopy and X-ray ...
